Hello :
the consecutive room numbers are : n , n+1
n(n+1) =420
n²+n -420 = 0
the discriminant delta = b² - 4ac ( a = 1 and b = 1 and c = - 420
delta = (1)²-4(1)(-420) =1681= 41²
n = (-1 -41)/2 ( refused negatif number)
or
n = (-1+41)/2 =20
<span> the room numbers.are : 20 , 21</span>
However many miles Jade hiked I would multiply it by however many times Gretta hiked to get your answer.
Answer:
(2,-9)
Step-by-step explanation:
A reflection around the x-axis implies keeping the x-coordinate as it its (no change in its numerical value), while using the exact opposite of the numerical value of the y coordinate.
In our case then:
X coordinate unaltered = 2 stays as 2
Y coordinate opposite of the original value: 9 changes to "-9"
Therefore the coordinates of point A' are: (2,-9)
Step-by-step explanation:
I don't exactly understand what you're asking, 36 feet does not need to be rounded to the nearest tenth as it is a whole number. Do you mean rounded to 40? (As that would be the nearsest multiple of 10) I'm a bit lost, but hopefully that helps
